Article
Bcl2 and p53 protein expression in metastatic carcinoma of unknown primary origin: Biological and clinical implications. A Hellenic co-operative oncology group study
(1998)We have previously shown that metastatic carcinomas of unknown primary site overexpress several tumor markers as well as the products of the oncogenes c-myc, ras and c-erbB2. We analysed the tissue expression of the protein ...

Article
Cancer of unknown primary site: Missing primary or missing biology?
(2007)Cancer of unknown primary site (CUP) ranks as the fourth most common cause of cancer deaths and represents both a diagnostic and a management challenge. In CUP, the regression or dormancy of the primary tumor, the development ...

Article
The clinical significance of bcl-2 overexpression in breast cancer patients - A retrospective study with long term follow up
(2001)We examined by immunohistochemistry the expression of the bcl-2 protein in sixty-eight cases of operated breast carcinoma patients (stage I, II and III) and correlated the findings with the prognosis. In 38.3% of the cases ...

Clinicopathologic study of vascular endothelial growth factor, thrombospondin-1, and microvessel density assessed by CD34 in patients with stage III ovarian carcinoma
(2006)The aim of the study was to investigate angiogenesis in patients with advanced-stage ovarian carcinoma. We used paraffin-embedded tumor tissues from 33 patients diagnosed with FIGO III ovarian cancer who had optimal surgery ...

Article
Clinicopathological study of metallothionein immunohistochemical expression, in benign, borderline and malignant ovarian epithelial tumors
(2006)Metallothioneins (MTs) are a family of cystein-rich metal-binding proteins, which are expressed in normal cells during fetal and postnatal life but also in a variety of human neoplasms. MT expression in human tumors has ...

Article
Clinicopathological study of the expression of hsp27, pS2, cathepsin D and metallothionein in primary invasive breast cancer
(2003)Expression of the hormone-related proteins hsp27, pS2, and also of cathepsin D (CD) and metallothionein (MT) was studied by immunohistochemistry and analyzed against clinical data in breast cancer. Archived material of ...

Article
Clinicopathological study of the expression of syndecan-1 in invasive breast carcinomas. Correlation with extracellular matrix components
(2004)Syndecan-1, a cell surface proteoglycan found predominantly on epithelia of mature tissues, binds both extracellular matrix (ECM) components and basic fibroblast growth factor (bFGF) and is implicated in the restriction ...

Article
DCC and TS protein expression in resected gastric cancer: A Hellenic Cooperative Oncology Group Study
(2008)There is a high risk of relapse after resection of gastric cancer. We studied the prognostic significance of the deleted colorectal cancer (DCC) gene and thymidylate synthase (TS) protein expression after resection of ...

Article
Depression in cancer: The many biobehavioral pathways driving tumor progression
(2017)Major Depressive Disorder (MDD) is common among cancer patients, with prevalence rates up to four-times higher than the general population. Depression confers worse outcomes, including non-adherence to treatment and increased ...

Article
The effect of the plasminogen activator inhibitor-1 4G/5G polymorphism on the thrombotic risk
(2008)Plasminogen activator inhibitor (PAI-1), is the central component of the fibrinolytic system. A deletion/insertion (4G/5G) polymorphism in the promoter region of the PAI-1 gene has been correlated with levels of plasma ...

Evaluation of the prognostic role of centromere 17 gain and HER2/topoisomerase II alpha gene status and protein expression in patients with breast cancer treated with anthracycline-containing adjuvant chemotherapy: Pooled analysis of two Hellenic Cooperative Oncology Group (HeCOG) phase III trials
(2013)Background: The HER2 gene has been established as a valid biological marker for the treatment of breast cancer patients with trastuzumab and probably other agents, such as paclitaxel and anthracyclines. The TOP2A gene has ...
